Reading from process pipes in IDL? [message #21797]

I have been trying to read image data from compressed (*.gz) files.

While this is possible with

SPAWN, "gunzip "+file+".gz"

OPENR, l, file, /GETLUN

READU, ....

FREE_LUN, l

I would prefer a way similar to PERL's

open(FILE, "gzip -cd $file |");

...

since it would not have to decompress/compress to disk.

Is this at all possible with IDL?
